Bug 16636: [QA Follow-up] Move External_BakerTaylor.t to t

When we mock the preferences completely now, we do not need
db access anymore.

Test plan:
Run the test without exporting KOHA_CONF.
The test passes with some warns about koha-conf.xml.
If you point KOHA_CONF to etc/koha-conf.xml, you have no warns.
